Dopamine Replacement Therapy Associated with Increase in Impulse Control Disorders Among Early Parkinson’s Disease Patients

WeintraubDaniel200x125.jpg

New Penn Medicine research shows that neuropsychiatric symptoms such as depression, anxiety and fatigue are more common in newly diagnosed Parkinson’s disease (PD) patients compared to the general population. The study also found that initiation of dopamine replacement therapy, the most common treatment for PD, was associated with increasing frequency of impulse control disorders and excessive daytime sleepiness. The new findings, the first longitudinal study to come out of the Parkinson's Progression Markers Initiative (PPMI), are published in the August 15, 2014, issue of Neurology®, the medical journal of the American Academy of Neurology.
